Matthew Sheffield brings up a really good point, and asks a great question.
Through May 3rd, 2016:

• 2016: Donald Trump won 40.4% of vote, everyone else 59.6%
• 2012: Mitt Romney won 37.5%, everyone else 62.5%

More people voted against Mitt Romney in ’12, than have voted against Donald Trump in 2016 –Data Here– So why wasn’t there a #NeverRomney movement?

What this reality actually does is destroy the current narrative and prove the #NeverTrump people are nothing more than DC beltway party ideologues and those who make a living from: 1) propping up the UniParty directly, or 2) giving the appearance to stand in opposition to the UniParty.
